Hello, I am doing some dev on the NRF51822 with a Cortex MO manager. I have trouble on the MISO pin, and I am wondering if I have to drive this MISO pin by any kind of pull up or down resistor. Thanks for you help

When nRF51 acts as master and slave is NOT selected, a slave's output is in a high impedance, so master's MISO input line won't have defined level and higher current (~tens of microamper, transient) consumption occurs.
Solution for nRF51 MISO input:
